LUBBICATOB. FOR ELEVATOR GUIDE-RAILS.

Specification of Letters Patent.

Patented Aug. 4, 1914.

Application filed January 24,1912. Serial N 0. 673,124.

To all whom it may concern:

Be it known that I, Loowrs Sorronrrrnrs, a citizen of the German Empire,residing at Frankfort-on-the-Main, Hesse-Nassau, Prussia, Germany, haveinvented certain new and useful Improvements in Lubricators for ElevatorGuide-Rails, of which the following is a specification.

Devices for lubricatingithe guide rails of elevators and the like whichare operated automatically by, means of projections arranged on thetrack, at intervals as far apart. as the necessity for lubricationdemands, are well known.

It is the object of this invention to produce an electrically operatedlubricating device consisting substantially of a lubricator carried bythe elevator and adapted to be operated by electric or magnetic actionexerted at suitable points along the guide rail.

It is especially desirable to exert this influence without any actualtouching of the movable lubricating device on the elevator, by thestationary electrical. devices located at intervals on the guide rails.

The invention will first be hereinafter more particularly described,with reference to the accompanyingdrawings, which form a part of thisspecification, and then POlIlllQd out in the claims at the end of thedescription.

In said drawings: Figure 1 is a top plan view of a permanent magnetsecured to the guide rail which is shownin section; Fig. 2 is a sideelevation ofthe lubricant container, showing also a portion of the guiderail, and a permanent magnet attached thereto, and Fig. 3 is a crosssection of a modification of the lubricant container shown in Fig. 2,with the temporary magnets attached thereto.

Referring to the drawings in which the same letters of referenceare usedto denote corresponding parts in different views, the letter a denotes aguide rail of an elevator car and h the surface for the lubricatingshoe. Instead of the usual mechanical pro jections on the guide railthere are provided at points where it is desired that lubrication shouldtake place, a magnet or magnets (Z having outside excitation andconnected in the electric circuit z'. In the lubricating apparatusitself there is provided a ratchetwheel 6 working through a shaft and atrain of gearing, upon a piston which is gradually forced downward intothe cylinder of the lubricating press, thus causing the lubricator to beforced out of the cylinder and onto the track, such a device being shownand described in my Patent No. 1,027, 909, dated h Iay 28, 1912. Theactuation of the ratchetwheel Z) is effected by means of a lever 0controlled by the spring Z andheld normally out of contact with themagnetic coil 0, the windings of which are connected with those of thecoil m.

The operation of the device is as follows: As the elevator or lift isdescending or ascending, the lubricating device carried by it willatcertain times reach a position adjacent or near the permanent magnets orcoils (Z, thereby causing an induced current in the coil m, which inturn will excite the coil 0 and cause the spring held lever 0 to beattracted toward it, thus throwing a pinion located on the other end ofthe lever against the ratchet wheel 6 through which a shaft and train ofgearing forces the piston downward in the cylinder, and the lubricatoroil onto the rails.

Fig. 3 shows a modification of thelubrieating mechanism. In thisconstruction a supply of oil is placed under spring pressure and shutoff from the lubricating shoe on the track by means of the cock p. Thiscock p has attached to one end a lever it held normally out of contactwith the coil '1) by means of the spring q, As has been explainedbefore, this lever a is drawn down an instant by means of the currentexcited in the coils during the motion of the coil or about the magnet(Z, thus turning the cook 79 and admitting the oil through the channelr, s, t, to thelubricating shoe. It will be observed that in thismodification the elec tric current merely releases the closure of theoil container and the oil is forced out on the track by spring pressureinstead of the electrically actuated devices first described.

Having thus described my invention, what I claim as new and desire tosecure by Let ters Patent of the United States is:

1. In a device of the character described, the combination with a trackand a shoe traveling thereon, of a lubricant container mounted on saidshoe, means for actuating said lubricant container comprising atemporary magnet carried by said shoe, a permanent magnet mounted onsaid track adapted to excite the temporary magnet in passingthe same,and means whereby the i T lever, a temporary magnet for actuating saidexcitation of the temporary magnet releases v wherebysaid lever isactuate the oil. y

2. In. a device ofthecharacter described,

the combination with a track and a shoe traveling thereon, of alubricant container mounted on said shoe a piston in said con.-

tainer, mechanism at the end of said container for moving said piston,including a lever, and means for rary magnet. l I I 3. In a device ofthe character described, thecombination with a track, of a lubricantcontainer adapted totr'avel back and forth on said track, mechanismcarried by said container for effecting a discharge of lubricant,including a temporary magnet, a lever held normally out of contact withsaid temporary magnet, and means mounted on said exciting saidtem'potrack for exciting said t mpor ry magnet 20 4. In a device ofthecharacter described, the combination with a track, of alubricantcontainer adapted to ttravel'back and forth on said track, meansqforeffecting a dis, charge of lubricant onto the track, consisting of alever, a temporaryimagnet, a periiiagnet and thereby drawing said levertoward said temporary magnet, and means for normally holding said leverout of contact with said temporary magnet.-
